About Jack Dulin

As a Technology Analyst at Infosys, contracted to Vanguard, I specialize in UI and API testing to automate processes, saving time and money while minimizing human errors. My role involves ensuring that Vanguard's retirement planning websites function flawlessly while ensuring they're accessible to people from all walks of life. In order to conduct automated UI testing to ensure the website functions as intended, I leverage Selenium scripts written in Java that are supported by the Maven and TestNG tools. For API testing, I use Postman to ensure that the API endpoints operate smoothly. At Vanguard, accessibility is seen as a crucial part of the functionality as opposed to an afterthought. I have employed NonVisual Desktop Access (NVDA), Color Contrast Analyzer (CCA), the ARC toolkit, and the AxeTools browser extension to ensure Vanguard fulfills its mission of providing a seamless user experience for visually and hearing-impaired individuals. Alongside my daily testing duties, I've also taken the initiative to develop and implement new features for our projects. I have modified the QMetry Automation Framework so that it could write metadata from Cucumber feature files along with API request and response data into extent reports, which capture the automated testing results. I have also implemented an AWS caching solution for retrieving secrets from AWS Secrets Manager that would reduce the number of API calls and cut AWS Secrets Manager-related costs by over 90%. Lastly, I have created a self-healing bot that would streamline the process of API testing by updating CSV, XML, JSON, and Cucumber feature files in response to changes made in a YAML specification file. Additionally, I've participated in a workplace hack-a-thon, utilizing AI agents written in Python to streamline test script generation. I've employed CrewAI agents that utilize tasks and custom tools to agentify each individual step of test script generation to make the process more scalable. I have created custom tools that will generate a screenshot of a webpage with a given URL and another custom tool that will capture a video recording of a Selenium script running by utilizing the OpenCV and NumPy libraries using a multi-threaded approach. My mission is to revolutionize automation processes, driving unparalleled efficiency and precision.
